Top 5 Wireshark Alternatives for Network Packet Capture

Wireshark is a widely used, free network packet capture tool that can intercept and display detailed information about all network traffic.

While classic, its functionality is not the most comprehensive, so here are five comparable tools worth collecting.

Savvius Omnipeek

Omnipeek is a paid solution offering a 30‑day free trial, with analysis capabilities that surpass Wireshark. It can detect packet issues, monitor throughput changes, and trigger alerts. The tool combines network management and packet capture, reporting end‑to‑end and link performance, and can generate on‑demand reports for web server interfaces. However, it runs only on 64‑bit Windows (7/8/10 or Windows Server 2008 R2‑2016) and not on Linux, Unix, or macOS.

Ettercap

Ettercap is a free, cross‑platform tool (Windows, Linux, Unix, macOS) that focuses on defensive functions. It uses the libpcap library to capture packets and can perform attacks such as ARP poisoning and MAC spoofing. Compared with Wireshark, Ettercap can capture SSL certificates, modify packet contents, delete connections, and capture passwords. It also isolates malicious users and records suspicious behavior, making it a more powerful option in many respects.

Kismet

Kismet cannot intercept wired traffic but excels at wireless packet sniffing on Linux, Unix, and macOS. Its data collector operates stealthily, so intrusion‑detection systems often miss its activity. By default, Kismet captures only packet headers, but it can also dump full payloads, analyze, sort, filter, and save packets to files.

SmartSniff

SmartSniff runs on Windows and supports wired networks; it can also capture on wireless networks if the Wi‑Fi adapter hosts the sniffing program. Although its native capture engine is limited, installing WinPcap enhances packet collection. Users can start and stop captures on demand, view connections in a top pane, and see traffic details in a bottom pane. The tool displays plain‑text traffic, hexadecimal dumps for encrypted packets, and allows filtering by TCP, UDP, or ICMP. Captured data can be saved to PCAP files for later analysis.

EtherApe

EtherApe is a free, cross‑platform tool (Linux, Unix, macOS) that builds a visual network map by collecting device messages and displaying hosts with their IP addresses. It captures all packets between hosts and shows real‑time traffic using color‑coded links representing protocols or applications. The map can track both wired and wireless networks, virtual machines, and underlying infrastructure, highlighting TCP/UDP flows and detecting IPv4/IPv6 addresses. Users can switch views to focus on specific connections or filter the map by source or application. EtherApe captures only packet headers, preserving data privacy.
